MikroTik

Posted: **Mon Mar 02, 2020 10:28 am**

Hello everyone!

I would like to know if someone here tried to configure/run ProtonVPN on Mikrotik routers.
According to ProtonVPN team it is not possible because most of Mikrotik routers support only PPTP connection protocol, which is not supported by ProtonVPN.
Have a great day!

Thank you.

That's just wrong. They say on their website:

We use only VPN protocols which are known to be secure - IKEv2/IPSec

RouterOS does support that: https://wiki.mikrotik.com/wiki/Manual:IP/IPsec

@normis: I agree with you. I will send to ProtonVPN's Team the link that you posted.
Normis, can you/we test to see how it works and what problems can arise, if they occur?

Thank you for your answer.

By looking at this example:
https://protonvpn.com/support/linux-ikev2-protonvpn/

it is very similar to nordvpn config, so you can use NordVPN RouterOS setup example as a reference:

Hi @normis,
Hi @mrz,

I'm posting the answer that I received from ProtonVPN:

We use only the highest strength encryption to protect your Internet connection. This means all your network traffic is encrypted with AES-256, key exchange is done with 4096-bit RSA, and HMAC with SHA384 is used for message authentication.

We have carefully selected our encryption cipher suites to only include ones that have Perfect Forward Secrecy. This means that your encrypted traffic cannot be captured and decrypted later if the encryption key from a subsequent session gets compromised. With each connection, we generate a new encryption key, so a key is never used for more than one session.

We use only VPN protocols which are known to be secure - IKEv2/IPSec and OpenVPN. ProtonVPN does not have any servers that support PPTP and L2TP/IPSec, even though they are less costly to operate. By using ProtonVPN, you can be confident that your VPN tunnel is protected by the most reliable protocol.

For more information, please refer to the following page: https://protonvpn.com/secure-vpn

Unfortunately, Mikrotik routers do not support OpenVPN client connection, therefore, it is not possible to set up a ProtonVPN connection on it. We're sorry for the inconveniences.

Please do not hesitate to contact us again if any additional information or assistance is needed.

Sad to see that such a reputable company has no understanding of their own products

MikroTik doesn't force anyone to use legacy insecure PPTP. We support IPsec. You can tell them that, looks like it's news for them.

Posted: **Mon Mar 02, 2020 1:11 pm**

Normis,
Maybe they do not know how to configure Mikrotik routers

, although I doubt it.
I already sent them a message with the links that you and mrz posted as a reply to my questions.
I will test on a Mikrotik router that I have and I will write, maybe, a tutorial on how to do it.
Thank you.

BTW OVPN is also supported, maybe they require some specific OVPN feature?

Maybe. However, below is the content of one of their config files:

Maybe you can spot some OVPN feature that is not yet implemented in ROS, although I doubt it.
Thank you

SHA512 is not supported and UDP is supported only in ROS v7

Posted: **Mon Mar 02, 2020 6:22 pm**

mrz,
You can connect using tcp protocol, but if they use in the config file the SHA512 then it's the same story.
However, if the SHA512 and UDP is not available in the current version of ROS and only in the v7 then in theory they are right.
Please correct me if I'm wrong.

Hello Guys,

I got this to work using the nordsvpn guide, initial I got:

ipsec first payload is NOTIFY

ipsec peer replied: NO_PROPOSAL_CHOSEN

But after a small tweak I got this to work.

Have you imported the root CA certificate, using which the server's certificate is signed, to the Mikrotik?

Posted: **Fri Jul 03, 2020 12:00 am**

Well what da-ya know?!?!?
I did it!!!!
Thanks Sindy. I had not done that part.
https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS
substitute for ProtonVPN, got an address (free server) in Netherlands
got my IKE details from my ProtonVPN account
Got cert from: https://protonvpn.com/download/ProtonVPN_ike_root.der

/tool fetch url=" https://protonvpn.com/download/ProtonVPN_ike_root.der"
/certificate import file-name=ProtonVPN_ike_root.der

Thanks to newbean for using his code. Think it's the same as the wiki. Not sure. If different then I may have mixed both sources up. Anyone stuck on this then drop me an IM and I'll post the code

Posted: **Fri Jul 03, 2020 12:23 am**

The free server is a bit funky.
I get some web pages working fine, Google webpage/search doesn't work at all. DNS does though although I use 8.8.8.8 and 1.1.1.1 so no idea if my dns switched provider.
This issue might be my config and not related to the free server.
Anyway, speedtest net mobile app ran at 2mbs down then failed the upload. After that, web pages started to fail for a few minutes.
I also got a strange leak, temporarily, as whatismyip changed back to UK. Maybe it was a cached result I don't know (one result only and occurred after the tunnel fail/stall - and I think the tunnel did drop for a moment and hence the reason for speedtest fail).
In the end I did get consistent NL ip addresses.

Will test some more

Posted: **Fri Jul 03, 2020 9:09 am**

As for the leaks, you have to make sure that while the VPN is down for any reason, packets are not routed the normal way via WAN. But because IPsec policy matching, and eventual packet redirection to the IPsec SA, requires that the packets were routed the normal way first, you need that the normal routing always sends them somewhere. The simplest way to achieve this is to add an /interface bridge without any member interfaces, and make it the gateway of the default route in a dedicated routing table for traffic which should only go via the VPN. Marking packets to use a specific routing table is called policy routing throughout Mikrotik documentation and it has nothing to do with IPsec policies. It is also possible to change the gateway of the default route in the main routing table and add dedicated routes towards the VPN server itself that use the default gateway, but with a DHCP client on WAN, this way is more complex than use of policy routing.

As for some sites working weird or not at all, there is the issue with path MTU discovery. When a packet sent by your PC is too large to fit to the WAN interface after getting wrapped into the IPsec headers and footers, the Mikrotik sends back an ICMP "fragmentation needed" message and the PC sends a smaller slice of the byte stream from the output buffer. But as the source address of that ICMP packet is Mikrotik's own one in the subnet where the PC is, and as the destination address of the IPsec policy is "anywhere", these packets are also redirected to the SA. Hence you have to place a static action=none src-address=0.0.0.0/0 dst-address=your.lan.sub.net/mask row into the /ip ipsec policy table before (above) the template from which the actual policy is generated when the IKEv2 connection establishes. The IPsec policy matching is done the same way like firewall rule matching, top to bottom until first match, so this added policy prevents packets sent by the router itself to its LAN clients from being redirected.

Hi Sindy,
Your second point about IPsec and mtu. I am confused.
I understand the mtu and your reasons but not sure how to solve it with the additional rule. Is that a firewall rule or something I setup in NAT or IPSEC?

Posted: **Fri Jul 03, 2020 11:48 pm**

My IPsec policy is a template.
Are you saying I create the exact same thing but set it as not a template and set action to none?

I don't understand that. You're suggesting that the ICMP packets are incorrectly being pushed through the tunnel instead of back to the lan

Posted: **Fri Jul 03, 2020 11:48 pm**

I understand the mtu and your reasons but not sure how to solve it with the additional rule. Is that a firewall rule or something I setup in NAT or IPSEC?

As I wrote, it is an IPsec policy, i.e. a row (or rule if you want) in the /ip ipsec policy table.

There are two types of rows in this table - actual policies and templates. The templates are used to create actual policies dynamically if /ip ipsec identity row permit this (and refers to a policy template group); the dynamically created policies appear after (below) the template from which they were created. So once you have the connection up, add the policy described above (an actual policy, not a template) and drag it above the template from which the dynamic policy has been created. As it is created manually, it survives a disconnection and re-connection of the IKEv2 session.

Posted: **Fri Jul 03, 2020 11:57 pm**

I don't understand that. You're suggesting that the ICMP packets are incorrectly being pushed through the tunnel instead of back to the lan

Not all ICMP packets. Only those sent by the Tik itself to the LAN clients, because the source address of these packets is from the LAN subnet, which you src-nat to the IP address assigned by the remote IPsec responder (server) by means of mode-config. So another possible remedy is to populate the address-list to which your mode-config row refers so that it would not contain the LAN IP of the Mikrotik itself.

Tunnel = un-ticked
Source = 0.0.0.0/0
Dest = 192.168.50.0/24
protocol = 255(all)
Template = un-ticked

Action = none
Level = require
IPsec Proto = esp
Proposal = ProtonVPNproposal or should this be default?

Posted: **Sat Jul 04, 2020 12:02 am**

Proposal = ProtonVPNproposal or should this be default?

For action=none, a proposal value is irrelevant. So if you cannot suppress it, use any value.

Posted: **Sat Jul 04, 2020 12:07 am**

Hey, that works.
Web pages are going through better and google now works.
Thanks - very much appreciated

Just ran speed tests to the free ProtonVPN in NL and it is doing 20mbs both ways. vast improvement

Posted: **Sat Aug 01, 2020 9:35 am**

I have managed to setup Proton VPN on Mikrotik according this thread, its working , but the connection drops approximately every 4 hours. There is no error, even if I enable ipsec debug log...

does anyone have a similar experience?

I've entered the setup and have a connection to the Proton server -

I want to send all my LAN(192.168.88.0/24) traffic over the VPN, so I entered the following from the Mikrotik Nord VPN example -

/ip firewall address-list add address=10.5.8.0/24 list=local

/ip ipsec mode-config set [ find name=ProtonVPN ] src-address-list=local

The NAT rule is shown as -

      chain=srcnat action=masquerade out-interface-list=WAN log=no log-prefix="" ipsec-policy=out,none

No LAN traffic is passing over the active VPN connection, what have I done wrong? Here is an image of my firewall rules -

From the bits of information you've posted instead of the complete configuration, I assume that you didn't get the purpose of setting the connection-mark in the /ip ipsec mode-config row.

You can use src-address-list, connection-mark, or both, but if you use both, packets need to match both to get src-nated by the dynamically created action=src-nat rule. Since you haven't posted any /ip firewall mangle rule, I assume you don't assign the connection-mark, so I guess it is enough to unset the connection-mark in the /ip ipsec mode-config row and you should be good.

If using connection-mark then you still have to mark traffic in Mangle.

The previous post suggested I unset the connection mark, it would be simplest if someone posted their working config including mangle rules etc.

I think you need to look at the link below to understand what needs to be sent via the tunnel - option 2 talks about MANGLE.. you need to do that for this to work
https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS

Posted: **Tue Aug 04, 2020 7:11 pm**

That suggesting was made to detect an error easier by having only one point of failure. Then you posted your config where looked for connection-marking in Mangle and found none.

The Wiki page linked to by Kams19 explains it in detail.

Is it possible for someone to write from A to Z how to set the VPN?
Thanks

Posted: **Thu Aug 06, 2020 2:01 pm**

Hello,

Issueing exactly the same commands posted by newbeen (with username and password adapted) the tunnel doesn't come up (ipsec active-peers table stays empty).

Is a particular version required (we use the latest LTS, 6.45.9)? Are additional packages needed (we only have basics, with hotspot, ipv6, mpls, ppp and routing disabled)? How can we access to a log (nothing appears on /log except for the audit of the configuration beeing issued) or even better a debug?

We are stuck ont the first part, establishing an IPSEC IKE v.2 tunnel; we aren't yet even facing the aspect of selecting which traffic to route towards the tunnel.

Thank you very much for your help.
A.V.

Vargas, email support with your config file (supout.rif).
as to ProtonVPN, the config should be nearly identical to NordVPN guide here:
https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS

also, enable more ipsec logs like this:

/system logging add topics=ipsec,!packet

From the bits of information you've posted instead of the complete configuration, I assume that you didn't get the purpose of setting the connection-mark in the /ip ipsec mode-config row.

You can use src-address-list, connection-mark, or both, but if you use both, packets need to match both to get src-nated by the dynamically created action=src-nat rule. Since you haven't posted any /ip firewall mangle rule, I assume you don't assign the connection-mark, so I guess it is enough to unset the connection-mark in the /ip ipsec mode-config row and you should be good.
I've tried removing the connection mark and traffic is still not being routed over the active VPN connection, any ideas? It's probably something simple, here's my router config -

OK, success ! I seem to be sending all traffic over the Proton VPN ... here is my config for anyone who is stuck -

I added the MSS clamp because there seemed to be an issue loading some pages ... but the config should still basically work without it. Think the old issue may have been the source address list I defined in ipsec mode config ... but not certain since I'm not an expert. Anyway it works now apparently(don't forget to load your certificates first).

Thank you very much for your availability.

I finally succeeded in establishing the tunnel (I forgot to add a rule to receive IKE replies on the INPUT chain of IPTABLES.

Now I will just follow the posted advices to understand how to select the traffic to encapsulate (through static routes or through iptables).

Thanks again.

I am kinda new to Mikrotik, so would appreciate if you've got this figured & fixed to post a little How To/ Tutorial/ Or key steps (maybe leverage an existing How To w some changes)?

From the bits of information you've posted instead of the complete configuration, I assume that you didn't get the purpose of setting the connection-mark in the /ip ipsec mode-config row.

Not sure if it's any help to you guys but SurfShark has a full on guide to setting up IKEv2 VPNs on their site, only issue I found was using the servers dns name drops every 5-10 seconds, but using the Ip address of that server works flawlessly. I'm getting around 250mbps between USA and Iceland, about 150mbps between USA and their multihops...

Have you imported Proton's root CA certificate to the Mikrotik?

Yes I have

OK. So first, confirm you have changed the password and/or username on the /ip ipsec identity row before posting the export; if you haven't, change the password at your Proton account (and update it in the identity on the Mikrotik).

Second, do the following:

disable the peer or identity representing the Proton VPN
issue a command /system logging add topics=ipsec,!packet
issue a command /log print follow-only file=ipsec-start where topics~"ipsec"
enable the peer or identity you have disabled in step 1
after 5 seconds, break the /log print ... command from step 3, download the file ipsec-start.txt and open it in your favourite text editor
find the EAP failed line and see what's next, there should be some details on the failure.

do you need more of the log??

The colon after "EAP failed" was promising, but as the log shows it was a notification from the server side, it is unlikely the log will shed more light on the reason of the failure. However, if you are absolutely sure that the username and loging are correct (e. g., do they use the same credentials for account management via web and for the VPN authentication?), do post the complete log, I dn't completely exclude that some hint can be found there.

Yes 100% sure of my credentials are entered correctly
no, account management and vpn credentials are diffrent

OK, I've missed that on your /ip ipsec identity row.

Remove the certificate item from there. The Proton's root CA certificate you have imported is used by your Mikrotik to verify validity of the certificate provided by the responder ("server") to authenticate itself to you. Your Mikrotik uses username and password, not certificate, to authenticate itself to the responder. By configuring a certificate, you tell it to use it instead, which confuses the responder. The fact that you've used the particular certificate for a wrong purpose is a secondary issue.

removed certificate from identity

The differences to my working ProtonVPN configuration are the following:

different ProtonVPN server used (different peer address)
eap-methods=eap-mschapv2,eap-peap,eap-ttls

As the guy above you is successful with eap-mschapv2 alone, I can't say which of the differences are more important. Maybe something has changed in the meantime.

Posted: **Mon Jan 11, 2021 6:58 pm**

hmm tried just for the fun of it to remove mschapv2 and added eap-peap,eap-ttls

now my log looks like this

Trying to connect to Proton VPN with hAP mini, but

/ip firewall nat print

returns:

As you can see - no dynamic "ipsec mode-config" NAT rule is created.
